本文对薄带(双辊)铸造法生产高锰钢带钢的性能进行了研究。为此，已使用实验室规模的双辊铸轧生产线和更传统的工艺链铸造了FeMn22C0.6带钢。试验表明，这两种方法生产高锰钢带钢是可行的。在显微组织和化学成分上的差异变得明显。铸锭和热成形生产的带材具有均匀的晶粒分布，而薄带铸造的带材具有典型的铸态组织，由树枝晶和球晶组织组成。另外，薄带铸钢含有准确的碳含量，而热成形路径会导致碳的损失，从而影响力学性能。证实了高锰钢薄带连铸的良好发展潜力，但仍需进一步完善。
In this paper, the capabilities of the thin strip (twin roller) casting method to produce high manganese steel strip are examined. For this purpose a FeMn22C0.6 strip has been cast both using a lab‐scale twin roll casting line and a more conventional process chain. The experiments show that the production of high manganese steel strip is feasible with both methods. Differences become apparent in the microstructure and chemical composition. While the strip which was produced by ingot casting and hot forming shows a homogenous grain distribution, the thin‐strip‐cast one shows a typical casting microstructure, consisting of dendritic and globulitic structures. In addition, the thin‐strip‐cast steel contains the accurate carbon content, while the hot forming route led to a loss of carbon, which influences the mechanical properties. The good potential of thin‐strip casting of high manganese steels, although it still has to be improved, is confirmed.
